"now charging, at a better rate”

David Coombs - Rieupeyroux (27/02/2017)

Shortly after receipt, our local garage fitted it, now charging, at a better rate, and can go out again. He tried on the internet to find a replacement for original, but no luck, I fared a LOT better. Had the Austin 8 since 1980, been here in France for 6 years now, used weekly in summer, monthly in winter -latter with 4/20 oil !! Thanks again, David Coombs
